Schrade takes assisted opening technology to the next level with these lightning-fast out-the-front pocket knives. These OTF pocket knives are as close as you can get to a fully automatic knife and still be legal. Simply release the safety lock mechanism, engage the blade actuator and watch as the spring mechanism deploys the blade into the locked and open position. The 3 2/5" AUS-8 serrated stainless steel blade is doubled edged and sharp on both sides with a piercing point and an anodized black finish. The rugged aluminum handle provides a secure, slip-free grip complete with a pocket clip and glass-breaking spike, and the sturdy safety lock prevents accidental misfires to ensure safe carrying.

I love all of schrade knives. I’ve gotten 3 different models and they all work great. I always carry one at home, work and every where else. All 3 models are different but can still be used one handed if you practice. Hoping to get all of them.

Schrade OTF knife review

The knife worked exactly the way I had hoped. The only issue I encountered with the knife was the need to work-in the retracting mechanism, but that is to be expected with any spring powered knife.

Not worth it !

Purchased the viper otf. Expected a knife of a higher quality, it is built quite nice , looks awesome. The spring is not strong enough to push the blade through paper, and the bladelock will not hold under any forward pressure.

Good for the price

Safety is almost useless on this product as it's harder to turn it back to the off position than it is to turn it on. Literallly. If anything so much as rubs it the right direction, boom! Safety off. Not to mention there isn't a secondary lock to keep the blade from sliding back once it's extended, it relies on a spring that is too weak to actually utilize the spear head without retracting back.
